Flatiron managed the team that designed and constructed the northwest portion of a new ring road around the city of Edmonton, Alberta. The new Northwest Anthony Henday Drive is a new 21-kilometer (13-mile) section of highway with two and three lanes that extends from Anthony Henday Drive at Yellowhead Trail on the west side of Edmonton to Manning Drive Freeway in the north.

The new road has nine interchanges, four flyovers, and two crossings over railways. Some crossings have multiple structures, bringing the total number of bridges to 29. With a 66 percent share, Flatiron led the joint venture.

This is the third portion of the ring road to be commissioned by the Alberta government. Flatiron managed the design-build team as part of the larger public-private partnership consortium NorthwestConnect.
